Answer: f(n)=2n+35

Step-by-step explanation:

Given : Let f(n) represent the total annual cost of renting n video games.

A video game club charges a fixed annual membership fee of $20 and $2 per video game rented.

Then the total annual cost is given by :-

f(n)=20+2n

If the membership was increased by $15 the next year , then the total cost in next years will be :-

f(n)=20+2n+15\\\\\Rightarrow\ f(n)=2n+35

Hence, the function best represents  the relationship between f(n) and n if the membership was increased by $15 the next year :

f(n)=2n+35

If the length of segment AC equals 58, what is the length of the midsegment DE
Delicious77 [7]

Answer:

B) 29

Step-by-step explanation:

Given:

AC= 58

Point D and E are the midpoints of side AB and BC Respectively.

Solution:

According to Midpoint theorem which states:

"The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side."

\therefore DE= \frac{1}{2} AC

DE= \frac{58}{2} =29

Hence length of DE is 29.
